Strawberry plant named &#39;carmela&#39;

ABSTRACT

Described is a strawberry variety having inflorescence about level with the foliage and abundant fruit production with early ripening.

BOTANICAL CLASSIFICATION

The present invention relates to a new Fragaria×ananassa Duch. plant.

VARIETAL DENOMINATION

The new plant has the varietal denomination ‘CARMELA’.

BACKGROUND OF THE INVENTION

The new variety of strawberry was created in a breeding program by crossing two parents; in particular, by crossing as seed parent an undistributed strawberry parent designated 86-032 (not patented) and as pollen parent an undistributed strawberry parent designated 9261 (not patented). Female is a component of a parent collection, from a selection made between plants issued from seeds in a free pollination in a population of different origin. Male is a selection from breeder's program of Planasa. Both parental varieties are proprietary and have not been commercialized, distributed or patented.

The resulting seedling of the new variety was grown and asexually propagated by runners in Soria, Spain, 3°W., 41°N., 3000 feet elevation. Clones of the new variety were further asexually propagated and extensively tested. This propagation and testing has demonstrated that the combination of traits disclosed herein which characterize the new variety are fixed and retained true to type through successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct strawberry variety. The varietal denomination of the new variety is ‘CARMELA’. Among the characteristics which appear to distinguish the new variety from other varieties are a combination of traits which include inflorescence that appears level with the foliage and abundant production of orange red colored, conical shaped, and very firm fruit, medium fruit size, and very early time of ripening (50% of plants with ripe fruits).

COMPARISON TO CLOSEST VARIETY

The new variety is closest to the variety ‘Tudnew’ (U.S. Plant Pat. No. 10,960), but is distinguished therefrom by the following characteristics possessed by ‘Carmela’ which are different than, or not possessed by, ‘Tudnew’ (U.S. Plant Pat. No. 10,960).

1. ‘Tudnew’ (U.S. Plant Pat. No. 10,960) exhibits a habit of plant flat globose than ‘Carmela’ exhibits a habit of plant globose.

2. ‘Tudnew’ (U.S. Plant Pat. No. 10,960) shows a leaf color of upper side (RHS green group near 138B to 138A) less dark than ‘Carmela’ (RHS green group near 131B to 135A).

3. Length/width ratio of the terminal leaflet in ‘Tudnew’ (U.S. Plant Pat. No. 10,960) is as long as broad, than in ‘Carmela’ it is longer than broad.

4. In ‘Tudnew’ (U.S. Plant Pat. No. 10,960) the position of the inflorescence relative to foliage is above. In ‘Carmela’ it is level with.

5. The attitude of hairs in ‘Tudnew’ (U.S. Plant Pat. No. 10,960) is slightly outwards, than in ‘Carmela’ it is upwards.

6. The fruit size of ‘Tudnew’ (U.S. Plant Pat. No. 10,960) is more large than of ‘Carmela’.

7. ‘Tudnew’ (U.S. Plant Pat. No. 10,960) shows a red fruit color (RHS red group near 42C to 42A), whereas in ‘Carmela’ it is an orange red fruit color (RHS orange red group near 33A to 34A).

8. The predominant shape of fruits of ‘Tudnew’ (U.S. Plant Pat. No. 10,960) is biconical, whereas in ‘Carmela’ it is conical.

The differences in the leaf color of upper side of the new variety and ‘Tudnew’ (U.S. Plant Pat. No. 10,960) are shown in FIGS. 2 and 3. The differences in the fruits of the new variety and ‘Tudnew’ (U.S. Plant Pat. No. 10,960) are shown in FIGS. 7, 8, and 9,10. These differences are maintained during the harvest season.

9. ‘Tudnew’ (U.S. Plant Pat. No. 10,960) shows a firmness fruit slightly more than ‘Carmela’ fruit.

10. Precocity in ‘Tudnew’ (U.S. Plant Pat. No. 10,960) is smaller than in ‘Carmela’.

BRIEF DESCRIPTION OF ILLUSTRATIONS

The accompanying photographs show typical specimens of the new variety, designated 98.08V.134 in the illustrations, including fruit, foliage and flower, in color as nearly true as it is reasonably possible to make in color illustrations of this character.

The plants depicted in the drawings were planted in October in the farm of La Mogalla in Cartaya (Huelva), Spain, about 7°W, 37°N, 45 feet elevation.

Drawings were taken in April: minimum temperate about 16° C. to 18° C., maximum temperate about 31 to 33° C.

FIG. 1 shows the undersurface of a typical terminal leaflet of the new variety (designated 98.08V.134) with a shape of base obtuse and in which the length/width ratio is longer than broad.

FIG. 2 shows the top and undersurface of a complete leave of the new variety (designated 98.08V.134).

FIG. 3 shows the top of a complete leave of ‘Tudnew’ (U.S. Plant Pat. No. 10,960) (designated 92.H1.51). In them we can see that the leaf color of upper side of ‘Tudnew’ (U.S. Plant Pat. No. 10,960) is less dark than ‘Carmela’.

FIGS. 4 and 5 show the fruit against a background of the top surface of the foliage of the new variety (designated 98.08V.134).

FIG. 6 shows the flower and reproductive organs of the new variety (designated 98.08V.134).

FIGS. 7 and 8 show typical fruit of the new variety (designated 98.08V.134) whole, sliced and in cross section, illustrating the typical flesh and flesh coloration, conspicuous core and core cavity, conical shape and orange red fruit color.

FIGS. 9 and 10 show typical fruit of the ‘Tudnew’ (U.S. Plant Pat. No. 10,960) (designated 92.H1.51) whole, sliced and in cross-section, illustrating the typical flesh and flesh coloration, conspicuous core and core cavity, biconical shape and red fruit color.

DESCRIPTION OF THE NEW VARIETY

The following detailed description of the new variety is based upon observations taken of plants and fruits grown “under glass”, i.e., under tunnel, in the farm of La Mogalla in Cartaya (Huelva), Spain, 7°W., 37°N., 45 feet elevation.

The following description is in accordance with UPOV terminology and the color terminology herein is in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.). The color descriptions and other phenotypical descriptions may deviate from the stated values and descriptions depending upon variation in environmental, seasonal, climatic and cultural conditions.

PROPAGATION

The new variety is principally propagated by way of runners. Although propagation by runners is presently preferred, other know methods of propagating strawberry plants may be used. Strawberries root well after transplanting.

The term “blistering” used herein refers to the texture or rugosity or surface ondulation inherent to leaves and is generally a constant characteristic.

GENERAL

‘Carmela’ is a short day variety that needs an induction to flowering by chilling, such as occurs at a high elevation nursery (fresh plant) or with cold storage (referred to as a frigo). Usually a short time is sufficient. ‘Carmela’ is self-fertile. It produces large quantity of pollen throughout the seasons and pollination is generally good as there are very few malformed fruit.
